SPECIFICATION forming part of Letters Patent No. 369,391, dated September 6, 1887.

Application filed November 13, 1856. Serial No. Qlji'l. (No model.)

To all whom. it may concern:

Beit known that l, Tr-rnoDonn BRUNNER, a citizen ot' the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, h ave invented certain new and use ful Improvements in llows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to plows, and has for its object to provide a plow with means for easily adjusting the mold-board from one side to the other to convert the plow into either a right or a left handed plow; also, with means to raise or lower the revolving colter so as to regulate the depth of cut of the plow; also, with means for locking the mold-board to whichever side it may be thrown; also, with means for bracing the mold-board from the landside, and also to generally simplify the construction without sacriiicing. the strength of the plow; and to such ends the invention consists in the construction and the combination of parts, hereinafter particularly described, and then sought to be specifically dened by the claims, reference being had to the accompanying drawings, forming part hereof, and in which- Figure l is a vertical section through the plow. Fig. 2 is a bottom View in perspective; Fig. 3, a horizontal section through the line :r .c of Fig. 1, with the inold-board in full lines on the left instead of the right of the plow. Fig. at is a detail view showing the notched bar p, passing through a guiding clip or loop, q, on the lever O.

The landside A of the plow is made in two parts, a and I), in the form of a box, with the two parts secured firmly together by suitable means-for instance, by screw-bolts c. Writhin the box is a sliding bolt, B, formed with a slot, d, for the guiding-pin e, with cog-teeth f for the cog-segment C to engage with, and at its rear with cog-teeth g for the cog-segment D to engage with. These teeth make the bolt a rackbar, which is moved back and forth by thc segment D, pivoted to the side of the box, with its lever E passed up through the top of the box and provided with alocking-inger, F, which engages with the segment h to hold the lever and the bolt to the position to which they are adj usted.

The handles G are secured to the brace-bars H, which are bolted to the standard I, and the mold-board J has a swiveled connection with the braces H, so that it may be swung from one side of the plow to the other. This swiveled connection may be effected by a collar, K, connected to the lower end of a lever and having a journal pin or stud, L, projecting from it, which enters a box, M, secured to the under side of the mold-board. This collar and pin converts the lower part of the lever into a crank, so as turn or swing the mold-board. The mold-board turns on the journatpin so as to adj ust itself to the necessary inclination when carried by the swivel or crank from one side of the plow to the other. I do not restrict myself to the particular construction of brace-bars, handle, and swivel described, as any equivalent arrangement will be included in the scope of my invention.

The lever N extends up from the swivel or crank, and is provided at its upper end with a crank-handle, 0,'and has a bearing in the beam P, so that by turning it the mold-board, when unlocked,will be carried under the beam, when what was its upper or mold-board portion will be carried down to form the point and share, and what was its share and point will be carried up on the other side to form the mold-board or turning portion of the plow.

The mold-board is guided in its movement from one side to the other by a grooved or hanged rod, track, or rail, Q, extending in a curved line across the underside of the board, with which engages a hook, R, projecting from the landside.

The mold-board is provided at corresponding points with loops or keepers S for the bolt or hook z' on the cog-segment C, to engage onwhichever side of the plow the mold-board may be thrown, so as to aid in locking the inold-board to its place. The mold-board is further provided at corresponding places near each point T with sockets U for the bolt B to shoot in to hold the mold-board in place.

A bracerod, V, is hinged-to a swivel, j, projecting from the landside, and is free to be thrown from one side of the plow to the other, so that a hook or point, 1c, may catch in au IOO eye or keeper, Z, secured to 'the mold-board on whichever side of the plow the mold-board may be.

The mold-board J, its points T, and share W are all made in one piece and substantially of the form shown, so that the parts will reverse when the board is turned from one side to the other of the plow.

The colter-roller m is journaled in an arm, X, pivoted to the beam I?, and to the upper endof the arm is connected a rod, n, which is connected at its opposite end to a lever, Y, fulcrumed to one of the braces Hand provided with a nger, o, to engage with a notched bar, p, to

hold the colter at the desired adjustment. The bar p is connected pivotally or otherwise at one end to the standard and at the other end passes through a clip or loop, q, which is connected to the lever O and serves as a support and guide to the bar. When the mold-board is to be turned, the lever is thrown toward the clevis end of the beam, so that the colter will be thrown up out of the way of the moldboard. A brace-bar, I?, may extend from the handles to the standard, so as to brace the handles.

When the mold-board is to be shifted, the brace V is disconnected from the eye, the colter is thrown forward, the trigger F is disengaged from the segment h, and the lever E thrown forward, which moves the bolt B back and away from the socket U, and at the same time draws the hook or bolt i out from the socket or keeper S, so that the braceV being disconnected from the mold-board) the crank O may be turned and the mold-board swung from one side to the other of the plow, when the bolt B will be moved forward into the socket U by means of the ,lever E, and the hook or bolt i at the same time thrown into the keeper S, thus locking the mold-board to its place.

It will be observed that the locking-bolts are confined within a boxing which protects them from injury, and that the locking and unlocking is easily and quickly effected and the mold-board shifted by simply turning the lever Y.

The parts combined as described form a strong, compact, and durable plow, simple and cheap to construct, and possessing merits apparent to the practical manufacturer and user.

I have described what I consider the best form and construction of the several parts,but do not confine myself thereto, as changes can be made without departing from the spirit of my invention.

Having described my invention and set forth its merits, what I claim is- 1. In a plow, the combination of the moldboard adapted to be swung beneath the beam from one side to the other of the plow, and a lever, as O, inclined as shown, and formed with a crank, as Il, at its lower end, to which crank said mold-board is connected, substantially as and for the purposes described.

2. In a plow, the combination of a moldboard adapted to be swung beneath the beam from one side to the other of the plow, and a lever, as O, having a crank at its lower end, with the mold-board swiveled to said crank, whereby the mold-board may be swung, as described, with one end raised as the other is being lowered, and be adjusted as described, and for the purposes set forth.

3. In a plow, the combination, with a moldboard adapted to be swung from one side to the other of the plow and provided with duplicate bolt-sockets, of a series of bolts, as B and i, adapted to be shotinto said sockets and withdrawn therefrom to whichever side the board is turned, and a lever for operating said bolts, substantially as described.

4. In a plow, the combination,with arnoldboard provided with bolt-sockets, of a hollow landside, a series of bolts within said landside, adapted to be shot into said bolt-sockets and withdrawn therefrom, and a lever for operating said bolts, substantially as described.

5. In a plow, the combination, with a moldboard provided with a boltsocket, of a hollow landside, a bolt contained therein, adapted to be shot into said socket and withdrawn therefrom, and a lever for operating said bolt, substantially as described.

6. In a plow, the combination, with amoldboard provided with sockets,of ahollow landside, a sliding bolt therein formed with teeth, a segment having teeth engaging those of the sliding bolt, and provided with a hook or point to engage with one of the sockets of the moldboard, and a lever connected with a segment having teeth engaging those of the sliding bolt for operating said bolt and through it the hook-segment, substantially as described.

7. In a plow, the combination, with amoldf board adapted to be swung from one side to the other of the plow and provided with a grooved or flanged rod or rail extending in a curved line across the board, of a landside and a hook to engage the rail to guide the moldboard, substantially as described.

8. In a plow, the combination,with the moldboard adapted to be swung from one side to the other of the plow and provided with an eye, Z, of a brace, V, hinged to a swivel connected to the landside and adapted to be swung -from one side to the other of the plow and provided with a hook end to be engaged with the eye on the mold-board, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
